Specification of Letters Patent. Patented Sept. 20, 1910.

Application filed January 15, 1910. Serial No. 588,239.

Be it known that I, JAMES I. Wooo, a citizen of the United States,residin at Salida, in the county of Chalfee and tate of. Colorado, haveinvented certain new and useful Improvements. in Explosive-Engines, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to improvements in explosive engines and itsobjects are to proean improved means for su plying a sufiicien'tquantity of air to the cy mder, 1mproved means for facilitating theexhaust of the burned gases, an improved means for supplying the oil andigniting the charge.

With the above and 0t er ob ects in view, the invention consists of thenovel construction, combination and arrangement of arts, hereinafterfullydescribed and claimed: and illustrated in the accompanying drawingsin which;

Figures 1 and 2 are side and top views of an fexplosi ve engineembodying my improvements; Fig. 3 1s a vertical longitudinal sectionthrough the cylinder and other parts of the engine; Fig. 4 is a verticaltransverse section taken on the plane indicated by the line l-4 in Fig.3; Fig. 5 is an end view of the cylinder with one of its heads removed;

Fig.6 is an'inner end view of the other head of the cylinder; Fig. 7 isa detail sectional view taken on the lane indicated by the line 7 --7 inFig. 3; the piston. Y

Referring ore particularly to the drawings 1 denotes the cylinder of myimproved engine and-2 and 3 denote the heads of the same. .The body 1 ofthe c' linder is preferably of cylinder shape an surrounded by a watercooling jacket 1 having upper and in the intermediate lower inlet andoutlet connections 5, 6. Instead of providing a single port or openingportion of the cylinder 1 for the inlet of air I em 10 a substantiallyannular series of re 1al y extending openings 7, the outer portions ofwhich comv inder 1 and they are closed by the head 2,

municate with lon itudinal assages 8 formed in the wane the cylin er andextending from the ports 7 to similar radial passa es 9 whichcommunicate with the rear end 0 the plylinder. The ortsor' assages 9 areforme by grooving the end 0 the cylig. 8 is a detail view of adjacentits rear end and air is adapted to be drawn by the piston through thisopening 13 and'to be then forced through the ports or 'assages 9, 8, 7,into the explosive end of t e cy inder in advance of the piston, aspresently explained. The exhaust passes out of the cylinder through twoopenin 14 arranged so that they converge in a sing e outlet ort or oening 15 formed in a boss at the Bottom 0 the cylinder about midway thelength of the latter. To deflect the exhaust gases toward the openings14 and defleet the air coming into the cylinder throughthe ports 7 theits end formed with a ro ecting deflecting rib 16, as shown in therawing.

On the outer end of the piston rod 11 is arranged a trunnion-carryinghead 17, the trunmons of which are pivoted in the arms,

suitable hearings on the bed and has at its ends the usual fly wheels22.

The head 3 of the cylinder is bolted or otherwise secured to the latterand consists of a circular plate, from the center of the outer face ofwhich rojects a. cylindrical enlargement 23 wh-ic contains a' centralbore or passage 24, an outer circular chamber 25, and an inner annularchamber 26. The chamber 26 communicates with the cylinder 1, and inconnection withthe bore or passage 24 forms a tubular projection 27against which oil is fed throu h a radial passage 28 formed in the circuar part or plate of the head 3. The outer annular r the outer endistonmay have chamber 25 is closed with the exception of its communicationwith the bore 2 and it is separated from the inner chamber 26 by aradial wall or shown in the drawing. Oil is supplied to the inlet 28from a force ump 30 arranged on one side of the cylin er and having adischarge pipe or connection 31 communipartition 29, as clearly eatingwith the passage or inlet 28 and an intake pipe or connection 32 leadingfrom a suitable oil tank or other source of supply. The piston of thepump 30 is con- .nected" to a slidable rod 33 which is actuated in onedirection by a surroundingcoil spring 34 and has at its free end aroller 35 tobear against an eccentrically arranged annular member or cam36 mounted for transverse sliding movement on the engine shaft '21 andheld normally in eccentric position by means of a coil spring arrangedon one of the guide pins which guide the cccentric-36 in its radialmove- ."through the plurality of radial ports or passages 7, at the sametime the exhaust gases passed through the converging outlet ports 14,which latter tend to muflie the exhaust and reduce noise. 011 theforward stroke .of the piston the charge is compressed in advance of thelatter and the heat in the boss or member-23 on the head 3 causes thecharge to be ignited. In starting the engine the member 23 must be firstheated to vaporize the oil which drops upon the tubular projection 27 inthe chamber 26, but after the engine has been started these parts willbe reheated at each explosion because the explosion will force the flameinto the bore 24 and chamber 25 to thoroughly heat .the parts of themember 23. It will be further understood that when the engine "is inoperation the oil dropping upon the heated tube 27 will quickly vaporizeand mingle with the charge of air.

\Vhile the preferred embodiment of the invention has been shown anddescribed in detail, it will be understood that I do not wish to belimited to the precise construction set forth, since various changesin'the form, roportion and arrangement of parts, and 1n the details ofconstruction, may be resorted. to within the spirit and scope of theinvention.

Having thus described the invention, what is claimed is: 4

1. In an explosive engine, the combination of a cylinder formed with atransverse row, of inlet ports intermediate its ends, a correspondingseries of radial ports, at one of its ends, and a series of longitudinalpassages connecting the-said parts, the cylindenbeing also formed. withan air inlet' port arranged adjacent the last mentioned end ofthccylinder, and an exhaust portarranged adjacent the first mentionedseries of inlet ports, a piston to reciprocate in the cylinder, a headupon one end of the cylinder and provided with an outwardly pro-'jecting boss containing a central bore and inner and outer chamberscommunicating with the bore, the inner chamber also 'communicating withthe cylinder and forming with the bore a tubular portion, said headbeing also formed with a radial oil inlet passage to discharge oil uponsaid tubular portion, and a pump actuated by the engine and adapted toforceoil through said oil passage.

, 2.In an explosive engine, the combinationof a cylinder. a head at oneend thereof 7 and provided with an outwardly extending enlargementcontaining a longitudinal bore and inner and outer chamberscommunicating with said bore, the inner chamber also communicating withthe cylinder and forming in connection with the bore a tubular portion,means for supplying oil to said tubular portion, and a piston to work insaid cylinder. p

3. In an explosive engine, the combina"- tion of a cylinder, a membercontaining a longitudinal bore and inner and outer chamberscommunicating with the bore, the inner chamber also communicating withthe cylinder and. forming in connection with the bore a tubular portion,and means for supplying oil to said tubular portion.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses. A JAMES I. WVOOD. Witnesses:
